Increase in Sensitivity by Base Clipping

Abstract

Theoretical and experimental research has been done on the use of base clipping of a signal confused by random noise to enhance the signal-to-noise ratio and hence to improve the detection probability. This investigation comprised a mathematical analysis of just how base clipping can be used to increase the sensitivity and in experimental verification based on both photographic and electronic methods. The theory and experiment agree quite closely and both indicate that an improvement of from 10 to 12 db in ultimate sensitivity can be achieved by base clipping.
